Changing default camera settings?
TLDR; create a camera with the settings you need and duplicate it when you need a new camera, so you'll have the right setting already there.

LONGER ANSWER AND PROCESS:

You can create a template .blend file where you have a set of cameras with the configuration you want to use (the same for objects).

Set this blend file as the default one (FILE > DEFAULT > SAVE STARTUP FILE). When you need to have a new camera, don't create it by scratch, but copy the one you have already in the blend file (main one, or another one hidden one in some collection you use as repository of different settings).

does it make sense to you?
